IMPROVEMENT IN COPINGS FOR WALLS.

Specification forming part of Letters Patent No. 115,653, dated J une 6,1871.

I, DANIEL M. SPROGLE, of Annapolis, in the county of Anne Arundel andState of Maryland, have invented an Improved (loping, of which thefollowing is a specification:

Nature and Objects of the Intention. My invention relates to an improvedcoping or capping for the tops of walls; the object of my inventionbeing to furnish a cheap, strong, and durable coping or capping, theblocks or sections forming which are capable of being firmly united toeach other for mutual support, the blocks or sections likewise beingcapable of being united to and combined with the wall in a firm andsolid manner, thereby providing, in addition to ornamentation, completeand lasting protection to the top, and hence in a great measure to theentire wall,

' whether constructed of brick or stone.

Description of the Accomm-nying Drawing. Like letters of referenceindicate like parts in the several figures. Figure 1 is an end elevationof coping embodyingmy invention. The coping Ais shown in this figureprovided with the projection,

tongue, or tenon, a, the longitudinal grooves" c, and the longitudinalhollow arch or groove cl, the coping A being combined with the wall B bymeans of cement, e, filling the longitudinal arch or groove d formed inthe coping A. Fig. 2- is a vertical longitudinal section of the same.The coping A is shown in this figure provided with the projections,tongues, or tenons, a, andthe corresponding recesses, grooves, ormortises, b, the coping A being combined with the walls B by means ofcement, e, filling the longitudinal arch or groove (1 formed in thecoping A.

General Description.

My improved copingAis made in blocks or sections, by the use of suitablemolds, of cement, concrete, or other artificial stone. In externalappearance, as regards form when placed in position, my coping does notdiffer from well-known coping, being made plain or with molded top oredges, or with both top and edges molded more or less ornamental, and inaccordance with the taste or fancy of the designer or manufacturer. Forthe purpose of firm combination and of causing my coping to furnishfuller protection from rains, &c., than is generally the case, I providethe ends of the blocks or sections forming the coping with theprojections and recesses, tongues and grooves, or tenons and mortises ab, that the blocks or sections, when placed for use, being properlyadjusted, may be securely combined by the use of cement. The blocks orsections thus mutually support each other, and the joints of the blocksor sections are thereby rendered impervious to water, whether in theform of rain or melted snow. For the more complete protection of the topof the wall, the entire wall thereby being protected in a greaterdegree, I provide my coping with the grooves a, formed in the block orsection on the under side, running longitudinally and not far from theouter edge, or between the outer edge and the point of juncture of thecoping and the vertical surface of the wall, there being formed at thatpoint either a right angle or an acute angle. For the purpose ofrendering the blocks or sections of less weight for transportation andhandling, but more especially for the purpose of uniting and combiningmy coping in a firm and solid manner to the wallthereby rendering itsattachment perfectly secure and the top of the wall throughout its wholelength thoroughly and completely protected from rains and melting snowsby means of the rounded mass of water-proof cement or artificial stone,that is formed, in the manner tween the outer groove 0. The centralhollow or groove d is so formed, preferably arched, that when, afterlaying the cement 6 upon the top of the wall to receive the blocks orsections of coping A, a ridge being heaped up along the middle, uponplacing the grooved block or section properly upon the cement,

. and pressing the section firmly, the central hollow or groove willreceive and be filled by the ridge of cement; or, when the block orsection of coping is placed upon the cemented top of the wall,additional material-either cement alone or cement combined with sand andgravel, or an equivalent materialmay be rammed horizontally, with anysuitable instrument, into the space formed by the hollowed block orsection of coping between the wall B and the surface of the hollowedportion d of the coping A.

What I claim as my invention, and desire to secure by Letters Patent, is

The artificial-stone coping-blocks herein described, provided with theprojections a, recesses b, and longitudinal hollow or groove 11,

constructed and arranged substantially as described and shown, formedeither with or with out the horizontal grooves a, and applied to andcombined with the tops of walls by the use of cement or equivalentmaterial, as degcrilfied and shown, and for the purpose set ort - DANIELM. SPROGLE.
